Enhancement of solar still performance using a reciprocating spray feeding system—An experimental approach

Techniques used to improve the performance of the stepped solar still—A review

“…For minimizing water depth in a stepped solar still El-Zahaby et al [15] created a thin re-established film of saline water by feeding the saline water into the still through a controlled transverse reciprocating spraying system (Fig. 15).…”

Performance evaluation of a continuous flow inclined solar still desalination system

“…The results showed that the modified still was efficient for produced water during the lack of sunlight especially at night. The performance of a stepped solar still using a spray seawater system was studied by El-Zahaby et al [13,14]. The results indicated that, the daily productivity and efficiency of the modified stepped still was higher than that for conventional still.…”

Productivity enhancement of a single basin and single slope solar still coupled with various basin materials

“…The basintype solar still with a water level of 1 cm and 3 cm test, showed that the minimum water level of 1 cm has the maximum productivity [15]. The saline water fed through a controlled transverse reciprocating spraying system to the corrugated steeped shape absorber of the solar still, gives an accumulated productivity of 6.355 l/m 2 /10 h, and the efficiency of the system has improved to 77.35%, when compared with the conventional still [16]. The solar radiation intensity is proportional to the still productivity [17].…”
